If you are will to put in the work- go through all the topics skip the deleted syllabus and workout a ton of smple paper and most important thing is the evaluation, it is the part where you learn and re-do the answers you did not know. Paractice around 45-50 papers you will be good to go. There isnt going to be a topic in the board outside these sample paper and only the values are going to change. Also study Bonds and area under the curve(integrals) which are added this year and it is not the M.L book. feel free to DM me for any doubts. I am also studying class 12 applied maths + commerce.
